IMPROVEMENT IN NOZZLES.

Specification forming part of Letters Patent No. 121,265, dated November28, 1871.

To all whom it may concern.-

Be it known that I, THoMAs WATsoN, of the city and county of Nevada,State of California, have invented an Improved Hydraulic Nozzle; and Ido hereby declare that the following description and accompanyingdrawing are sufficient to enable any person skilled in the art orscience to which it mostnearly appertains to make and use my saidinvention or improvements without further invention or experiment.

My improvement in hydraulic nozzles relates more particularly to thatclass of nozzles which is employed for throwing a large stream of waterfrom a hydraulic pipe for the purpose of hydraulic mining 5 and its objeot is to concentrate the stream inside of the nozzle so that it will beejected in a solid body and in a direct line without twisting.

In order to more fully illustrate and explain my invention, reference ishad to the accompanying drawing forming a part of this specification, inwhich A represents a hydraulic nozzle of the class above mentioned. Thisnozzle is constructed with an enlargement at some point between the baseand small end of the nozzle so as to form a chamber, 1), of greaterdiameter than the remain der of the nozzle. The location of this chambershould be a short distance back of the discharge end of the nozzle, sothat the water which collects in it will serve to pack the stream whichpasses directly through the nozzle, and, by avoid ing the passage of thestream along a curved metallic surface, do away with the twisting of thestream, by which its efficiency is greatly impaired.

By this means I do away with the twisting of the stream without the useof the radial plates which are frequently used for this purpose, therebyavoiding the objection to the use of these plates, which is theirliability of being knocked out or becoming displaced, or bent by theforce of the stream, so that they have to be frequently repaired.

By using the chamber there will be no obstruction in the pipe to catchleaves and brush, which are often carried through by the stream.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

A hose-pipe nozzle having a double truncated cone near its connectionwith the hose, and narrowing by a more obtuse line of con traction fromthe extremityofsuclitriincated cone to the point of delivery, allasshown and described.

In witness whereof I have hereunto set my hand and seal.
